You can feed them a variety of high quality tropical fish flakes, bloodworms, brine shrimp , and daphnia . If the tropical flakes are too big, you can break them into tiny pieces in your hand first before feeding it to them.

Tetras are mostly carnivorous so the bloodworms you used for feeding your goldfish are just fine for feeding them too.

Avoid feeding them goldfish food (flakes) since it contains more vegetable matter and a higher fat content.

Flakes? Tropical fish flakes are the most obvious option d: And yes, like nabi says, they can eat a number of live foods as long as you're cutting the food a bit smaller for them There are special tropical fish flakes for carnivorous fish, and these flakes are usually red, you could try and check them out, they should be perfect for the tetras

Got tiny pellets for tropical fish from the petshop today, suitable for Bettas and Tetras, etc.Now, how much does a Betta eat per day? How often do you feed your Bettas per day? I gave him a small pinch this evo, perhaps about 7 pellets (granules) he ate them fairly quick

My little neons go ape over the Aqueon tropical flakes (there was a $2 off coupon in my Aqueon 10 gallon tank kit and I bought the $3.50 size). I had some Omega One Veggie flakes that I feed my goldies on their vegetable days, and the neons just turned their little noses at it. My glofish love it as well. It's so funny, I watch the hyper fish for a bit then look at the goldie tank, to see them moving at such a slow pace. I love all my fishies!
